kernel-ci are happy to receive hardware. I've sent them boards in the
past which have been added to their test farm. Kernel-ci is mostly
about boot testing, but they do do some tests post boot. So if you can
supply tests as well, they may run them for you.

How much of this do you already have automated test for?  You can also
setup your own test farm, using the kernels kernel-ci builds.
